MGC3140 MGC3140 3D Tracking and Gesture Controller Product

Brief

Introduction

Microchip’s MGC3140 is a 3D gesture and motion tracking controller based on Microchip’s patentedGestIC® technology – suitable for consumer, industrial and automotive applications. It enables robust userinterfaces with natural hand and finger movements utilizing the principles of electrical near-field sensing.

Implemented as a low-power mixed-signal configurable controller, the MGC3140 provides a compellingset of smart functional features such as gesture recognition while using adaptive working frequencies forrobust performance in noisy environments. Microchip’s on-chip Colibri gesture suite removes the need forhost post-processing and reduces system power consumption, resulting in low software developmentefforts for short time-to-market success.

The MGC3140 represents a unique and high-performance single-chip gesture solution focusing onautomotive applications. MGC3140 provides proximity, gesture detection and driver recognition, thusenabling modern and compelling user interfaces to be created.

MGC3140


1. Key Features• Automotive Qualification AEC Q100 Grade 1• Recognition of 3D Hand Gestures and x, y, z Positional Data• Proximity and Touch Sensing• Built-in Colibri Gesture Suite (running on-chip)• Advanced 3D Signal Processing Unit• Detection Range: 0 to 10 cm, typical• Receiver Sensitivity:

2. Functional DescriptionMicrochip Technology’s GestIC technology utilizes electrical near-field (E-field) sensing. The chip isconnected to electrodes that are sensing the E-field variance. The GestIC device then calculates theuser’s hand motion relatively to the sensing area in x, y, z position data, and classifies the movementpattern into gestures in real time. In addition, by utilizing the principles of E-field sensing, the GestICsystem is immune to ambient influences such as light or sound, which have a negative impact on themajority of other 3D technologies. Also, it allows full-surface coverage of the electrode area with nodetection blind spots of a user’s action.

Microchip Technology’s MGC3140 is a configurable controller. Featuring a Signal Processing Unit (SPU),a wide range of 3D gesture applications are being processed on the MGC3140, which allows shortdevelopment cycles. Always-on 3D sensing is enabled, even for battery-driven devices, by the chip’s low-power design and the variety of programmable power modes. GestIC sensing electrodes are driven by alow-voltage signal with frequencies of 42, 43, 44, 45, and 100 kHz, allowing their electrical conductivestructure to be made of any low-cost material.
